Cate Blanchett has revealed she likes to make the most of her post-sex glow by going make-up free

While answering a question about the best advice she has received from a make-up artist, the Aussie told the fashion bible: "It’s not necessarily how much of or what the product is that she’s putting on but it’s the way it’s applied.

"Don’t you find, if you’ve just had sex or you’ve just had a really great massage, you could go out to dinner without a lick of make-up on and people go ‘My god, you look fabulous’ because you’re relaxed.”

Her honesty continued when she was asked about the most "outlandish" beauty treatment she had tried.

The Oscar-winner revealed she sees the same facialist as Sandra Bullock in New York for a treatment they have nicknamed the "penis facial".

She explained: "Sandy [Sandra] Bullock and I saw this facialist in New York, Georgia Louise, and she gives what we call the penis facial and it’s something – I don’t know what it is, or whether it’s just cause it smells a bit like sperm – there’s some enzyme in it so Sandy refers to it as the penis facial."

Cate also added she was a fan of an all-over body scrub in a rather unusual location.

She said: "I really, really love when you land somewhere and it’s usually New York or LA and you go straight to those 24 hour Korean spas and you get pummelled by those fantastic Korean women and they rub you with what feels like a Brillo pad.
